| Pyrite filiform chabazite |
This sample is part of the reason that I have not blogged for a while. The other reason is that Carol, my wife, has been very ill, and the final reason is that I have struggled with my equipment. It seems like I have been forgetting how to run it.
The two needles are, one with a cross section of a square and the other the cross section of bar.

| Pyrite filiform chabazite |
The pyrite filiform has been difficult for me to find. That coupled with my ineptitude held me back.
The chemical formula for it is FeS2, Iron Di-sulfide. Pyrite is fairly common but the filiform of it is rare. It has been called Fool's Gold. When we were young my brother made a "crystal radio" It had germanium diode detector. Pyrite can be as sensitive as that. The radio had a "cat whisker" which the diode.

| Pyrite filiform chabazite Camera Setup |
For a time I had to revert to using flash in order to stop vibrations in my setup. That was a big bit of encouragement. Later I learned to make settings in my camera, mirror lock, and time for the vibrations to subside between captures.
